Stop learning math concepts by solving problems!
First of all, make sure you understand the concept!
Math is about internalizing concepts by solving problems and understanding them!
The most important concepts in math explained in an easy-to-understand way!

1.
An explanation method that approaches familiar everyday language and explains mathematical terms again.

Mathematics was created naturally to solve problems in everyday life.
Therefore, the terms used in mathematics are words that naturally emerged to explain something.
It may seem difficult and complicated, but if you know the exact meaning of the word, you can understand what it is, and even go a step further and naturally understand its nature.
This book presents concepts using everyday language familiar to children, with illustrations to aid understanding.
After that, we will explain the concept again using strict mathematical terms.
This way of organizing the explanation will have the effect of first seeing the forest of mathematics and then immediately following that, seeing the trees of mathematics one by one.

2.
Problems that make the concept completely mine!

Are you memorizing "problem-solving methods" by repeatedly solving problems without reading the explanations? This book organizes the problems into steps so you can practice the concepts step by step.
Solving any problem requires going through several stages of thinking.
From simple problems to those that require multiple steps to find the answer, the concepts are arranged step by step so that you can fully digest and absorb them.
